问题 How do I use the admin action to create a queryset which will apply a Many-to-Many value? I understand the 'value' will have to already exist (in my case, the colour itsel will have to exist).

问题 I wonder if anyone would know a way to return the categories related to the session chosen in the select options. Example: class Session(models.Model): name = models.CharField("Sessão", max_length=100) slug = models.SlugField("Slug", max_length=100) class Category(models.Model): session = models.ForeignKey(Session, verbose_name='Sessão', on_delete=models.CASCADE, max_length=100, default=1, blank=True, null=True) category = models.CharField("Categoria", max_length=100) slug = models.SlugField(

阅读更多关于 Feeding a current filter selection to another custom SimpleListFilter in Django

问题 I am trying to make the prompts of one filter change in response to the current selection made in another filter. I am pretty lost as to how to get the currently selected value of the AttributeCategoryFilter passed into the AttributeFilter. I am using Django 1.4-dev. Trying to figure out if I should be using RelatedFieldListFilter for this purpose. It looks like these features are so young as to not have (m)any examples floating around in the wild yet. class AttributeCategoryFilter

django admin list_filter “or” condition

阅读更多关于 django admin list_filter “or” condition

问题 sorry if this question has been answered before, but I did a lot of googling without success. I know how to create custom list_filter s in admin views (e.g. subclassing SimpleFilter ). What I really would like, is a way (on the admin list view) to "check" different filters that combines them in a OR formula. As an example, suppose you have: # models.py class Foo(models.Model): foobar = ... foofie = ... ... # admin.py class FooAdmin(admin.ModelAdmin): list_filter = ( "foobar", "foofie" ) ...

问题 So the title is a bit obtuse, I know, but I couldn't think of a more succinct way to state it. Here's the issue: I've created two proxy models for "user types", both inheriting from django.contrib.auth.User. Each has a custom manager limiting the queryset to items belonging to a particular Group.
